Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company Capital One Financial Corporation, a Delaware Corporation established in 1994 and headquartered in McLean, Virginia, is a diversified financial services holding company with banking and non-banking subsidiaries. Capital One Financial Corporation and its subsidiaries (the “Company”) offer a broad array of financial products and services to consumers, small businesses and commercial clients through branches, the internet and other distribution channels. As of March 31, 2019 , our principal subsidiaries included: • Capital One Bank (USA), National Association (“COBNA”), which offers credit and debit card products, other lending products and deposit products; and • Capital One, National Association (“CONA”), which offers a broad spectrum of banking products and financial services to consumers, small businesses and commercial clients. The Company is hereafter collectively referred to as “we,” “us” or “our.” COBNA and CONA are collectively referred to as the “Banks.” We also offer products outside of the United States of America (“U.S.”) principally through Capital One (Europe) plc (“COEP”), an indirect subsidiary of COBNA organized and located in the United Kingdom (“U.K.”), and through a branch of COBNA in Canada. COEP has authority, among other things, to provide credit card loans. Our branch of COBNA in Canada also has the authority to provide credit card loans. Our principal operations are organized for management reporting purposes into three major business segments, which are defined primarily based on the products and services provided or the type of customer served: Credit Card, Consumer Banking and Commercial Banking. We provide details on our business segments, the integration of recent acquisitions, if any, into our business segments and the allocation methodologies and accounting policies used to derive our business segment results in “ Note 13—Business Segments and Revenue from Contracts with Customers .” Basis of Presentation and Use of Estimates The accompanying unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”). The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and in the related disclosures. These estimates are based on information available as of the date of the consolidated financial statements. While management makes its best judgments, actual amounts or results could differ from these estimates. In the opinion of management, all normal, recurring adjustments have been included for a fair statement of this interim financial information. Certain prior period amounts have been reclassified to conform to the current period presentation. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements, and related notes thereto, included in Capital One Financial Corporation’s 2018 Annual Report on Form 10-K (“2018 Form 10-K”). Newly Adopted Accounting Standards Standard Guidance Adoption Timing and Financial Statements Impacts Premium Amortization on Callable Debt Accounting Standards Update (“ASU”) No. 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities Issued March 2017 Shortens the amortization period from the contractual life to the earliest call date for certain purchased callable debt securities held at a premium. We adopted this guidance in the first quarter of 2019 using the modified retrospective method of adoption. Our adoption of this standard did not have a material impact on our consolidated financial statements. Leases ASU No. 2016-02, Leases (Topic 842) Issued February 2016 Requires lessees to recognize right of use assets and lease liabilities on their consolidated balance sheets and disclose key information about all their leasing arrangements, with certain practical expedients. We adopted this guidance in the first quarter of 2019, using the modified retrospective method of adoption without restating prior periods. We elected the practical expedients that permitted us to not reassess the lease classification of existing leases, whether existing contracts contain a lease or the treatment of initial direct costs on existing leases. Upon adoption, we recorded a lease liability of $1.9 billion and right of use asset of $1.6 billion, which is net of other lease-related balances. Accounting Standards Issued but Not Adopted as of March 31, 2019 Standard Guidance Adoption Timing and Financial Statements Impacts Cloud Computing ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract Issued August 2018 Aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Effective January 1, 2020, with early adoption permitted, using either the retrospective or prospective method of adoption. We plan to adopt the standard on its effective date and are currently evaluating the expected impact of such adoption. Goodwill Impairment Test Simplification ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment Issued January 2017 Eliminates the second step from the current goodwill impairment test. Under the current guidance, the first step compares a reporting unit’s carrying value to its fair value. If the carrying value exceeds fair value, an entity performs the second step, which assigns the reporting unit’s fair value to its assets and liabilities, including unrecognized assets and liabilities, in the same manner as required in purchase accounting. Under the new guidance, any impairment of a reporting unit’s goodwill is determined based on the amount by which the reporting unit’s carrying value exceeds its fair value, limited to the amount of goodwill allocated to the reporting unit. Effective January 1, 2020, with early adoption permitted, using the prospective method of adoption. We plan to adopt the standard on its effective date and do not expect such adoption to have a material impact on our consolidated financial statements. Standard Guidance Adoption Timing and Financial Statements Impacts Current Expected Credit Loss (“CECL”) ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Issued June 2016 Requires the use of current expected credit loss model that is based on expected rather than incurred losses to determine our allowance for credit losses on financial assets measured at amortized cost, certain net investments in leases and certain off-balance sheet arrangements. Replaces current accounting for PCI and impaired loans. Amends the other-than-temporary impairment model for available for sale debt securities to require that credit losses (and subsequent recoveries) be recorded through an allowance approach, rather than through permanent write-downs for credit losses and subsequent accretion of positive changes through interest income over time. Effective January 1, 2020, with early adoption permitted no earlier than January 1, 2019, using the modified retrospective method of adoption. We plan to adopt the standard on its effective date. We have established a company-wide, cross-functional governance structure for our implementation of this standard. We continue to evaluate industry accounting interpretations, data requirements and necessary changes to our credit loss estimation methods, processes, systems and controls. We have commenced limited parallel testing and expect to perform multiple tests of our full end-to-end allowance process prior to adopting the standard. We continue to assess the potential impact on our consolidated financial statements, related disclosures and regulatory capital. We currently expect our adoption of this guidance will result in an increase to our reserves for credit losses on financial instruments due to the requirement to record expected losses over the remaining contractual lives of our financial instruments; however, the actual impact will depend on the characteristics of our financial instruments, economic conditions, and our economic and loss forecasts at the adoption date.

Leases [Abstract]
Leases	NOTE 2—LEASES Leases In the first quarter of 2019, we adopted ASU No. 2016-02, Leases (Topic 842). See “Note 1—Summary of Significant Accounting Policies” for the impacts upon adoption. Our primary involvement with leases is in the capacity as a lessee where we lease premises to support our business. A majority of our leases are operating leases of office space, retail bank branches and Cafés. For these leases, we have elected to account for the lease and non-lease components together as a single lease component. Our operating leases expire at various dates through 2071 without taking into consideration available renewal options, and many of them require variable lease payments by us, of property taxes, insurance premiums, common area maintenance and other costs. Certain of these leases also have extension or termination options, and we assess the likelihood of exercising such options. If it is reasonably certain that we will exercise the options, we include the impact in the measurement of our right-of-use assets and lease liabilities. Our right-of-use assets and lease liabilities for operating leases are included in other assets and other liabilities on our consolidated balance sheet. As most of our operating leases do not provide an implicit rate, we use our incremental borrowing rate in determining the present value of lease payments. Our operating lease expense is included in occupancy and equipment within non-interest expense in our consolidated statements of income. Total operating lease expense consists of operating lease cost, which is recognized on a straight-line basis over the lease term, and variable lease cost, which is recognized based on actual amounts incurred. We also sublease certain premises and sublease income is included in other non-interest income. The following tables present our operating lease portfolio and related lease costs as of and for the three months ended March 31, 2019 . Table 2.1 Operating Lease Portfolio (Dollars in millions) March 31, 2019 Right-of-use assets $ 1,547 Lease liabilities 1,836 Weighted average remaining lease term 9.2 years Weighted average discount rate 3.3 % Table 2.2 Total Operating Lease Expense and Other Information (Dollars in millions) Three Months Ended March 31, 2019 Operating lease cost $ 65 Variable lease cost 11 Total lease cost 76 Sublease income (6 ) Net lease cost $ 70 Cash paid for amounts included in the measurement of lease liabilities $ 82 Right-of-use assets obtained in exchange for lease liabilities 15 Right-of-use assets recognized upon adoption of new lease standard 1,601 The following table presents a maturity analysis of our operating leases and a reconciliation of the undiscounted cash flows to our lease liabilities as of March 31, 2019 .

These right-of-use assets and lease liabilities are included in premises and equipment, net and other borrowings on our consolidated balance sheets. We recognized $5 million of total finance lease expense for the three months ended March 31, 2019

Investment Securities	NOTE 3—INVESTMENT SECURITIES Our investment securities portfolio consists primarily of the following: U.S. Treasury securities; U.S. government-sponsored enterprise or agency (“Agency”) and non-agency residential mortgage-backed securities (“RMBS”); Agency commercial mortgage-backed securities (“CMBS”); and other securities. Agency securities include Government National Mortgage Association (“Ginnie Mae”) guaranteed securities, Federal National Mortgage Association (“Fannie Mae”) and Federal Home Loan Mortgage Corporation (“Freddie Mac”) issued securities. The carrying value of our investments in U.S. Treasury and Agency securities represented 96% of our total investment securities as of both March 31, 2019 and December 31, 2018 . We classify investment securities as either available for sale or held to maturity.

Maturities and Yields of Investment Securities The table below summarizes, by major security type, the contractual maturities and weighted-average yields of our investment securities as of March 31, 2019 . Because borrowers may have the right to call or prepay certain obligations, the expected maturities of our securities are likely to differ from the scheduled contractual maturities presented below. The weighted-average yield below represents the effective yield for the investment securities and is calculated based on the amortized cost of each security.

Other-Than-Temporary Impairment We evaluate all securities in an unrealized loss position at least quarterly, and more often as market conditions require, to assess whether the impairment is other-than-temporary. Our OTTI assessment is based on a discounted cash flow analysis which requires careful use of judgments and assumptions. A number of qualitative and quantitative criteria may be considered in our assessment, as applicable, including the size and the nature of the portfolio; historical and projected performance such as prepayment, default and loss severity for the RMBS portfolio; recent credit events specific to the issuer and/or industry to which the issuer belongs; the payment structure of the security; external credit ratings of the issuer and any failure or delay of the issuer to make scheduled interest or principal payments; the value of underlying collateral; our intent and ability to hold the security; and current and projected market and macro-economic conditions. If we intend to sell a security in an unrealized loss position or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, the entire difference between the amortized cost basis of the security and its fair value is recognized in earnings. As of March 31, 2019 , we had sold all securities previously designated with the intent to sell, and did not intend to sell, nor believe that we will be required to sell, any other security in an unrealized loss position prior to the recovery of its amortized cost basis. For those securities that we do not intend to sell nor expect to be required to sell, an analysis is performed to determine if any of the impairment is due to credit-related factors or whether it is due to other factors, such as interest rates. Credit-related impairment is recognized in earnings, with the remaining unrealized non-credit-related impairment recorded in AOCI. We determine the credit component based on the difference between the security’s amortized cost basis and the present value of its expected cash flows, discounted at the security’s effective yield. Realized Gains and Losses on Securities and OTTI Recognized in Earnings The following table presents the gross realized gains or losses and proceeds from the sale of securities available for sale for the three months ended March 31, 2019 and 2018 . We did not recognize any OTTI and did not sell any investment securities that are classified as held to maturity for the three months ended March 31, 2019 and 2018 .

Securities Pledged and Received We pledged securities available for sale and held to maturity totaling $15.9 billion and $16.3 billion as of March 31, 2019 and December 31, 2018 , respectively. These securities are pledged to primarily secure FHLB advances and Public Funds deposits, as well as for other purposes as required or permitted by law. We accepted pledges of securities with a fair value of $1 million as of both March 31, 2019 and December 31, 2018 , primarily related to our derivative transactions.

Loans	NOTE 4—LOANS Loan Portfolio Composition Our loan portfolio consists of loans held for investment, including loans held in our consolidated trusts, and loans held for sale, and is divided into three portfolio segments: credit card, consumer banking and commercial banking. Credit card loans consist of domestic and international credit card loans. Consumer banking loans consist of auto and retail banking loans and in prior periods also consisted of home loans. Commercial banking loans primarily consist of commercial and multifamily real estate as well as commercial and industrial loans. We sold all of our consumer home loan portfolio and the related servicing during 2018. The information presented in this section excludes loans held for sale, which are carried at lower of cost or fair value. Credit Quality March 31, 2019 and December 31, 2018 . The delinquency aging includes all past due loans, both performing and nonperforming.

We pledged loan collateral of $15.3 billion and $15.8 billion to secure a portion of our FHLB borrowing capacity of $18.8 billion and $19.3 billion as of March 31, 2019 and December 31, 2018 , respectively. We also pledged loan collateral of $8.4 billion and $9.2 billion to secure our Federal Reserve Discount Window borrowing capacity of $7.0 billion and $7.6 billion as of March 31, 2019 and December 31, 2018 , respectively. In addition to loans pledged, we securitized a portion of our credit card loans. See “ Note 6—Variable Interest Entities and Securitizations March 31, 2019 and December 31, 2018 . Nonperforming loans generally include loans that have been placed on nonaccrual status. PCI loans are excluded from the table below.

We therefore generally manage credit risk based on portfolios with common risk characteristics. The risk in our credit card loan portfolio correlates to broad economic trends, such as unemployment rates and home values, as well as consumers’ financial condition, all of which can have a material effect on credit performance. The primary indicators we assess in monitoring the credit quality and risk of our credit card portfolio are delinquency and charge-off trends, including an analysis of loan migration between delinquency categories over time. The table below displays the geographic profile of our credit card loan portfolio as of March 31, 2019 and December 31, 2018 .

Net charge-off rate is calculated by dividing annualized net charge-offs by average loans held for investment for the period for each loan category. Our consumer banking loan portfolio consists of auto and retail banking loans. Similar to our credit card loan portfolio, the risk in our consumer banking loan portfolio correlates to broad economic trends, such as unemployment rates, gross domestic product and home values, as well as consumers’ financial condition, all of which can have a material effect on credit performance. Delinquency, nonperforming loans and charge-off trends are key indicators we assess in monitoring the credit quality and risk of our consumer banking loan portfolio.

(2) We evaluate the credit risk of commercial loans using a risk rating system. We assign internal risk ratings to loans based on relevant information about the ability of the borrowers to repay their debt. In determining the risk rating of a particular loan, some of the factors considered are the borrower’s current financial condition, historical and projected future credit performance, prospects for support from financially responsible guarantors, the estimated realizable value of any collateral and current economic trends. The scale based on our internal risk rating system is as follows: • Noncriticized: Loans that have not been designated as criticized, frequently referred to as “pass” loans. • Criticized performing: Loans in which the financial condition of the obligor is stressed, affecting earnings, cash flows or collateral values. The borrower currently has adequate capacity to meet near-term obligations; however, the stress, left unabated, may result in deterioration of the repayment prospects at some future date. • Criticized nonperforming: Loans that are not adequately protected by the current net worth and paying capacity of the obligor or the collateral pledged, if any. Loans classified as criticized nonperforming have a well-defined weakness, or weaknesses, which jeopardize the full repayment of the debt. These loans are characterized by the distinct possibility that we will sustain a credit loss if the deficiencies are not corrected and are generally placed on nonaccrual status. We use our internal risk rating system for regulatory reporting, determining the frequency of credit exposure reviews, and evaluating and determining the allowance for loan and lease losses for commercial loans. Generally, loans that are designated as criticized performing and criticized nonperforming are reviewed quarterly by management to determine if they are appropriately classified/rated and whether any impairment exists. Noncriticized loans are also generally reviewed, at least annually, to determine the appropriate risk rating.

Allowance for Loans and Lease Losses	NOTE 5—ALLOWANCE FOR LOAN AND LEASE LOSSES AND RESERVE FOR UNFUNDED LENDING COMMITMENTS Our allowance for loan and lease losses represents management’s best estimate of incurred loan and lease losses inherent in our loans held for investment portfolio as of each balance sheet date. In addition to the allowance for loan and lease losses, we also estimate probable losses related to unfunded lending commitments, such as letters of credit, financial guarantees and binding unfunded loan commitments. The provision for losses on unfunded lending commitments is included in the provision for credit losses in our consolidated statements of income and the related reserve for unfunded lending commitments is included in other liabilities on our consolidated balance sheets. See “ Note 1—Summary of Significant Accounting Policies ” in our 2018 Form 10-K for further discussion of the methodology and policy for determining our allowance for loan and lease losses for each of our loan portfolio segments, as well as information on our reserve for unfunded lending commitments. Allowance for Loan and Lease Losses and Reserve for Unfunded Lending Commitments Activity The table below summarizes changes in the allowance for loan and lease losses and reserve for unfunded lending commitments by portfolio segment for the three months ended March 31, 2019 and 2018 .

We have certain credit card partnership agreements that are presented within our consolidated financial statements on a net basis, in which our partner agrees to share a portion of the credit losses on the underlying loan portfolio. The expected reimbursements from these partners, which are netted against our allowance for loan and lease losses, result in reductions to net charge-offs and provision for credit losses. See “ Note 1—Summary of Significant Accounting Policies ” in our 2018 Form 10-K for further discussion of our credit card partnership agreements. The table below summarizes the changes in the estimated reimbursements from these partners for the three months ended March 31, 2019 and 2018 .

Variable Interest Entities and Securitization [Abstract]
Variable Interest Entities and Securitizations	NOTE 6—VARIABLE INTEREST ENTITIES AND SECURITIZATIONS In the normal course of business, we enter into various types of transactions with entities that are considered to be VIEs. Our primary involvement with VIEs has been related to our securitization transactions in which we transferred assets to securitization trusts. We have primarily securitized credit card loans, which have provided a source of funding for us and enabled us to transfer a certain portion of the economic risk of the loans or related debt securities to third parties. The entity that has a controlling financial interest in a VIE is referred to as the primary beneficiary and is required to consolidate the VIE. The majority of the VIEs in which we are involved have been consolidated in our financial statements. Summary of Consolidated and Unconsolidated VIEs The assets of our consolidated VIEs primarily consist of cash, credit card loan receivables and the related allowance for loan and lease losses, which we report on our consolidated balance sheets under restricted cash for securitization investors, loans held in consolidated trusts and allowance for loan and lease losses, respectively. The assets of a particular VIE are the primary source of funds to settle its obligations. Creditors of these VIEs typically do not have recourse to our general credit. Liabilities primarily consist of debt securities issued by the VIEs, which we report under securitized debt obligations on our consolidated balance sheets. For unconsolidated VIEs, we present the carrying amount of assets and liabilities reflected on our consolidated balance sheets and our maximum exposure to loss. Our maximum exposure to loss is estimated based on the unlikely event that all of the assets in the VIEs become worthless and we are required to meet our maximum remaining funding obligations. The tables below present a summary of VIEs in which we had continuing involvement or held a variable interest, aggregated based on VIEs with similar characteristics as of March 31, 2019 and December 31, 2018 . We separately present information for consolidated and unconsolidated VIEs. Table 6.1 : Carrying Amount of Consolidated and Unconsolidated VIEs March 31, 2019 Consolidated Unconsolidated (Dollars in millions) Carrying Amount of Assets Carrying Amount of Liabilities Carrying Amount of Assets Carrying Amount of Liabilities Maximum Exposure to Loss Securitization-Related VIEs: Credit card loan securitizations (1) $ 32,729 $ 19,809 $ 0 $ 0 $ 0 Home loan securitizations 0 0 175 32 496 Total securitization-related VIEs 32,729 19,809 175 32 496 Other VIEs: (2) Affordable housing entities 242 13 4,395 1,323 4,395 Entities that provide capital to low-income and rural communities 1,728 108 0 0 0 Other 0 0 530 0 530 Total other VIEs 1,970 121 4,925 1,323 4,925 Total VIEs $ 34,699 $ 19,930 $ 5,100 $ 1,355 $ 5,421 December 31, 2018 Consolidated Unconsolidated (Dollars in millions) Carrying Amount of Assets Carrying Amount of Liabilities Carrying Amount of Assets Carrying Amount of Liabilities Maximum Exposure to Loss Securitization-Related VIEs: Credit card loan securitizations (1) $ 33,574 $ 18,885 $ 0 $ 0 $ 0 Home loan securitizations 0 0 211 74 554 Total securitization-related VIEs 33,574 18,885 211 74 554 Other VIEs: (2) Affordable housing entities 243 17 4,238 1,303 4,238 Entities that provide capital to low-income and rural communities 1,739 117 0 0 0 Other 0 0 353 0 353 Total other VIEs 1,982 134 4,591 1,303 4,591 Total VIEs $ 35,556 $ 19,019 $ 4,802 $ 1,377 $ 5,145 __________ (1) Represents the carrying amount of assets and liabilities owned by the VIE, which includes the seller’s interest and repurchased notes held by other related parties. (2) In certain investment structures, we consolidate a VIE which in turn holds as its primary asset an investment in an unconsolidated VIE. In these instances, we disclose the carrying amount of assets and liabilities on our consolidated balance sheets as unconsolidated VIEs to avoid duplicating our exposure, as the unconsolidated VIEs are generally the operating entities generating the exposure. The carrying amount of assets and liabilities included in the unconsolidated VIE columns above related to these investment structures were $2.3 billion of assets and $845 million of liabilities as of March 31, 2019 and $2.3 billion of assets and $811 million of liabilities as of December 31, 2018 . Securitization-Related VIEs In a securitization transaction, assets are transferred to a trust, which generally meets the definition of a VIE. Our primary securitization activity is in the form of credit card securitizations, conducted through securitization trusts which we consolidate. Our continuing involvement in these securitization transactions mainly consists of acting as the primary servicer and holding certain retained interests. We transfer multifamily commercial loans that we originate to the government-sponsored enterprises (“GSEs”) and retain the right to service the transferred loans pursuant to the guidelines set forth by the GSEs. Subsequent to such transfers, these loans are commonly securitized into CMBS by the GSEs. We also hold RMBS and CMBS in our investment securities portfolio, which represent an interest in the respective securitization trusts employed in the transactions under which those securities were issued. We do not consolidate the securitization trusts employed in these transactions as we do not have the power to direct the activities that most significantly impact the economic performance of these securitization trusts. Our maximum exposure to loss as a result of our involvement with these VIEs is the carrying value of MSRs and investment securities on our consolidated balance sheets. See “ Note 7—Goodwill and Intangible Assets ” for information related to our MSRs associated with these multifamily commercial loan securitizations and “ Note 3—Investment Securities ” for more information on the securities held in our investment securities portfolio. We exclude these VIEs from the tables within this note because we do not consider our continuing involvement with these VIEs to be significant as we either invest in securities issued by the VIE and were not involved in the design of the VIE or no transfers have occurred between the VIE and us. In addition, where we have certain lending arrangements in the normal course of business with entities that could be VIEs, we have also excluded these VIEs from the tables presented in this note. See “ Note 4—Loans ” for additional information regarding our lending arrangements in the normal course of business. The table below presents our continuing involvement in certain securitization-related VIEs as of March 31, 2019 and December 31, 2018 . Table 6.2 : Continuing Involvement in Securitization-Related VIEs (Dollars in millions) Credit Card Mortgages March 31, 2019: Securities held by third-party investors $ 19,273 $ 1,183 Receivables in the trust 31,682 1,209 Cash balance of spread or reserve accounts 0 116 Retained interests Yes Yes Servicing retained Yes Yes (1) December 31, 2018: Securities held by third-party investors $ 18,307 $ 1,276 Receivables in the trust 34,197 1,305 Cash balance of spread or reserve accounts 0 116 Retained interests Yes Yes Servicing retained Yes Yes (1) __________ (1) We retain servicing on a portion of our remaining mortgage loans in mortgage securitizations. Credit Card Securitizations We securitize a portion of our credit card loans which provides a source of funding for us. The credit card securitizations involve the transfer of credit card receivables from our balance sheet to securitization trusts. These trusts then issue debt securities collateralized by the transferred receivables to third-party investors. We hold certain retained interests in our credit card securitizations and continue to service the receivables in these trusts. We consolidate these trusts because we are deemed to be the primary beneficiary as we have the power to direct the activities that most significantly impact the economic performance of the trusts, and the right to receive benefits or the obligation to absorb losses that could potentially be significant to the trusts. Mortgage Securitizations We had previously securitized mortgage loans by transferring these loans to securitization trusts that had issued mortgage-backed securities to investors. These mortgage trusts consist of option-adjustable rate mortgage (“option-ARM”) securitizations and securitizations from our discontinued operations which include the mortgage origination operations of our wholesale mortgage banking unit, GreenPoint Mortgage Funding, Inc. (“GreenPoint”) and the manufactured housing operations of GreenPoint Credit, LLC, a subsidiary of GreenPoint (collectively “GreenPoint securitizations”). We continue to service a portion of the remaining mortgage loans in the option-ARM securitizations and also retain rights to certain future cash flows arising from these securitizations. We also retain servicing on a portion of the remaining mortgage loans in the GreenPoint securitizations and have the right to receive any funds remaining in the pre-funded letters of credit after the securities are released. We do not consolidate the mortgage securitizations because we do not have the right to receive the benefits nor the obligation to absorb losses that could potentially be significant to the trusts or we do not have the power to direct the activities that most significantly impact the economic performance of the trusts. Other VIEs Affordable Housing Entities As part of our community reinvestment initiatives, we invest in private investment funds that make equity investments in multifamily affordable housing properties. We receive affordable housing tax credits for these investments. The activities of these entities are financed with a combination of invested equity capital and debt. We account for certain of our investments in qualified affordable housing projects using the proportional amortization method if certain criteria are met. The proportional amortization method amortizes the cost of the investment over the period in which the investor expects to receive tax credits and other tax benefits, and the resulting amortization is recognized as a component of income tax expense attributable to continuing operations. For the three months ended March 31, 2019 and 2018 , we recognized amortization of $143 million and $124 million , respectively, and tax credits of $171 million and $146 million , respectively, associated with these investments within income tax provision. The carrying value of our equity investments in these qualified affordable housing projects was $4.3 billion and $4.2 billion as of March 31, 2019 and December 31, 2018 , respectively. We are periodically required to provide additional financial or other support during the period of the investments. Our liability for these unfunded commitments was $1.5 billion as of both March 31, 2019 and December 31, 2018 and is largely expected to be paid from 2019 to 2021 . For those investment funds considered to be VIEs, we are not required to consolidate them if we do not have the power to direct the activities that most significantly impact the economic performance of those entities. We record our interests in these unconsolidated VIEs in loans held for investment, other assets and other liabilities on our consolidated balance sheets. Our maximum exposure to these entities is limited to our variable interests in the entities which consisted of assets of approximately $4.4 billion and $4.2 billion as of March 31, 2019 and December 31, 2018 , respectively. The creditors of the VIEs have no recourse to our general credit and we do not provide additional financial or other support other than during the period that we are contractually required to provide it. The total assets of the unconsolidated VIE investment funds were approximately $10.8 billion as of both March 31, 2019 and December 31, 2018 , respectively. Entities that Provide Capital to Low-Income and Rural Communities We hold variable interests in entities (“Investor Entities”) that invest in community development entities (“CDEs”) that provide debt financing to businesses and non-profit entities in low-income and rural communities. Variable interests in the CDEs held by the consolidated Investor Entities are also our variable interests. The activities of the Investor Entities are financed with a combination of invested equity capital and debt. The activities of the CDEs are financed solely with invested equity capital. We receive federal and state tax credits for these investments. We consolidate the VIEs in which we have the power to direct the activities that most significantly impact the VIE’s economic performance and where we have the obligation to absorb losses or right to receive benefits that could be potentially significant to the VIE. We have also consolidated other investments and CDEs that are not considered to be VIEs, but where we hold a controlling financial interest. The assets of the VIEs that we consolidated, which totaled approximately $1.7 billion as of both March 31, 2019 and December 31, 2018 , respectively, are reflected on our consolidated balance sheets in cash, loans held for investment, and other assets. The liabilities are reflected in other liabilities. The creditors of the VIEs have no recourse to our general credit. We have not provided additional financial or other support other than during the period that we are contractually required to provide it. Other Other VIEs include variable interests that we hold in companies that promote renewable energy sources and other equity method investments. We were not required to consolidate these entities because we do not have the power to direct the activities that most significantly impact their economic performance. Our maximum exposure to these entities is limited to the investment on our consolidated balance sheets of $530 million and $353 million as of March 31, 2019 and December 31, 2018

Deposits and Borrowings [Abstract]
Deposits and Borrowings	NOTE 8—DEPOSITS AND BORROWINGS Our deposits represent our largest source of funding for our assets and operations, which include checking accounts, money market deposits, negotiable order of withdrawals, savings deposits and time deposits. We also use a variety of other funding sources including short-term borrowings, senior and subordinated notes, securitized debt obligations and other borrowings. In addition, we utilize FHLB advances, which are secured by certain portions of our loan and investment securities portfolios. Securitized debt obligations are presented separately on our consolidated balance sheets, as they represent obligations of consolidated securitization trusts, while federal funds purchased and securities loaned or sold under agreements to repurchase, senior and subordinated notes and other borrowings, including FHLB advances, are included in other debt on our consolidated balance sheets. Our total short-term borrowings generally consist of federal funds purchased, securities loaned or sold under agreements to repurchase, and short-term FHLB advances. Our long-term debt consists of borrowings with an original contractual maturity of greater than one year. The following tables summarize the components of our deposits, short-term borrowings and long-term debt as of March 31, 2019 and December 31, 2018 . The carrying value presented below for these borrowings includes unamortized debt premiums and discounts, net of debt issuance costs and fair value hedge accounting adjustments.

Derivative Instruments and Hedg

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	NOTE 9—DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Use of Derivatives and Accounting for Derivatives We regularly enter into derivative transactions to support our overall risk management activities. Our primary market risks stem from the impact on our earnings and economic value of equity due to changes in interest rates and, to a lesser extent, changes in foreign exchange rates. We manage our interest rate sensitivity by employing several techniques, which include changing the duration and re-pricing characteristics of various assets and liabilities by using interest rate derivatives. We also use foreign currency derivatives to limit our earnings and capital exposures to foreign exchange risk by hedging exposures denominated in foreign currencies. In addition to interest rate and foreign currency derivatives, we may also use a variety of other derivative instruments, including caps, floors, options, futures and forward contracts, to manage our interest rate and foreign exchange risks. We designate these risk management derivatives as either qualifying accounting hedges or free-standing derivatives. Qualifying accounting hedges are further designated as fair value hedges, cash flow hedges or net investment hedges, and free-standing derivatives are economic hedges that do not qualify for hedge accounting. We also offer various interest rate, commodity and foreign currency derivatives as accommodation to our customers within our Commercial Banking business. We enter into these derivatives with our customers primarily to help them manage interest rate risks, hedge their energy and other commodities exposures, and manage foreign currency fluctuations. We then enter into offsetting derivative contracts with counterparties to economically hedge the majority of our subsequent exposures. See below for additional information on our use of derivatives and how we account for them: • Fair Value Hedges: We designate derivatives as fair value hedges when they are used to manage our exposure to changes in the fair value of certain financial assets and liabilities, which fluctuate in value as a result of movements in interest rates. Changes in the fair value of derivatives designated as fair value hedges are presented in the same line item on our consolidated statements of income as the earnings effect of the hedged items. Our fair value hedges consist of interest rate swaps that are intended to modify our exposure to interest rate risk on various fixed-rate financial assets and liabilities. • Cash Flow Hedges: We designate derivatives as cash flow hedges when they are used to manage our exposure to variability in cash flows related to forecasted transactions. Changes in the fair value of derivatives designated as cash flow hedges are recorded as a component of AOCI. Those amounts are reclassified into earnings in the same period during which the forecasted transactions impact earnings and presented in the same line item on our consolidated statements of income as the earnings effect of the hedged items. Our cash flow hedges use interest rate swaps and floors that are intended to hedge the variability in interest receipts or interest payments on some of our variable-rate financial assets or liabilities. We also enter into foreign currency forward contracts to hedge our exposure to variability in cash flows related to intercompany borrowings denominated in a foreign currency. • Net Investment Hedges: We use net investment hedges to manage the foreign currency exposure related to our net investments in foreign operations that have functional currencies other than the U.S. dollar. Changes in the fair value of net investment hedges are recorded in the translation adjustment component of AOCI, offsetting the translation gain or loss from those foreign operations. We execute net investment hedges using foreign currency forward contracts to hedge the translation exposure of the net investment in our foreign operations under the forward method. • Free-Standing Derivatives: Our free-standing derivatives primarily consist of our customer accommodation derivatives and other economic hedges. The customer accommodation derivatives and the related offsetting contracts are mainly interest rate, commodity and foreign currency contracts. The other free-standing derivatives are primarily used to economically hedge the risk of changes in the fair value of our commercial mortgage loan origination and purchase commitments as well as other interests held. Changes in the fair value of free-standing derivatives are recorded in earnings as a component of other non-interest income. Derivatives Counterparty Credit Risk Counterparty Types Derivative instruments contain an element of credit risk that arises from the potential failure of a counterparty to perform according to the terms of the contract. We execute our derivative contracts primarily in over-the-counter (“OTC”) markets. We also execute minimal amounts of interest rate and commodity futures in the exchange-traded derivative markets. Our OTC derivatives consist of both centrally cleared and uncleared bilateral contracts. In our centrally cleared contracts, our counterparties are central counterparty clearinghouses (“CCPs”), such as the Chicago Mercantile Exchange (“CME”) and the LCH Group (“LCH”). In our uncleared bilateral contracts, we enter into agreements directly with our derivative counterparties. Counterparty Credit Risk Management We generally manage our counterparty credit risk associated with derivative instruments by entering into legally enforceable master netting arrangements, where possible, and exchanging margin and collateral with our counterparties, typically in the form of cash or high-quality liquid securities. The amount of collateral exchanged is dependent upon the fair value of the derivative instruments as well as the fair value of the pledged collateral. When valuing collateral, an estimate of the variation in price and liquidity over time is subtracted in the form of a “haircut” to discount the value of the collateral pledged. Our exposure to derivative counterparty credit risk, at any point in time, is equal to the amount reported as a derivative asset on our balance sheet. The fair value of derivatives is adjusted on an aggregate basis to take into consideration the effects of legally enforceable master netting agreements and any associated cash collateral received or pledged. See Table 9.3 for our net exposure associated with derivatives. The terms under which we collateralize our exposures differ between cleared exposures and uncleared bilateral exposures. • CCPs : We clear eligible OTC derivatives with CCPs as part of our regulatory requirements. Futures commission merchants (“FCMs”) serve as the intermediary between CCPs and us. CCPs require that we post initial and variation margin through our FCMs to mitigate the risk of non-payment or default. Initial margin is required upfront by CCPs as collateral against potential losses on our cleared derivative contracts. Variation margin is exchanged on a daily basis to account for mark-to-market changes in the derivative contracts. For CME and LCH-cleared OTC derivatives, we characterize variation margin cash payments as settlements. Our FCM agreements governing these derivative transactions include provisions that may require us to post additional collateral under certain circumstances. • Bilateral Counterparties : We generally enter into legally enforceable master netting agreements and collateral agreements, where possible, with bilateral derivative counterparties to mitigate the risk of default. We review our collateral positions on a daily basis and exchange collateral with our counterparties in accordance with these agreements. These bilateral agreements typically provide the right to offset exposure with the same counterparty and require the party in a net liability position to post collateral. Agreements with certain bilateral counterparties require both parties to maintain collateral in the event the fair values of derivative instruments exceed established exposure thresholds. Certain of these bilateral agreements include provisions requiring that our debt maintain a credit rating of investment grade or above by each of the major credit rating agencies. In the event of a downgrade of our debt credit rating below investment grade, some of our counterparties would have the right to terminate the derivative contract and close out the existing positions. Credit Risk Valuation Adjustments We record counterparty credit valuation adjustments (“CVAs”) on our derivative assets to properly reflect the credit quality of the counterparty. We consider collateral and legally enforceable master netting agreements that mitigate our credit exposure to each counterparty in determining CVA, which may be adjusted in future periods due to changes in the fair values of the derivative contracts, collateral and creditworthiness of the counterparty. We also record debit valuation adjustments (“DVAs”) to adjust the fair values of our derivative liabilities to reflect the impact of our own credit quality. We calculate this adjustment by comparing the spreads on our credit default swaps to the discount benchmark curve. Balance Sheet Presentation The following table summarizes the notional and fair values of our derivative instruments as of March 31, 2019 and December 31, 2018 , which are segregated by derivatives that are designated as accounting hedges and those that are not, and are further segregated by type of contract within those two categories. The total derivative assets and liabilities are adjusted on an aggregate basis to take into consideration the effects of legally enforceable master netting agreements and any associated cash collateral received or pledged. Derivative assets and liabilities are included in other assets and other liabilities, respectively, on our consolidated balance sheets.

The amortized cost basis of this portfolio was $8.7 billion and $8.3 billion , the amount of the designated hedged items was $4.2 billion and $4.0 billion , and the cumulative basis adjustment associated with these hedges was $71 million and $26 million as of March 31, 2019 and December 31, 2018 , respectively. (2) Carrying value represents amortized cost. Balance Sheet Offsetting of Financial Assets and Liabilities Derivative contracts and repurchase agreements that we execute bilaterally in the OTC market are generally governed by enforceable master netting arrangements where we generally have the right to offset exposure with the same counterparty. Either counterparty can generally request to net settle all contracts through a single payment upon default on, or termination of, any one contract. We elect to offset the derivative assets and liabilities under netting arrangements for balance sheet presentation where a right of setoff exists. For derivative contracts entered into under master netting arrangements for which we have not been able to confirm the enforceability of the setoff rights, or those not subject to master netting arrangements, we do not offset our derivative positions for balance sheet presentation. The following table presents as of March 31, 2019 and December 31, 2018 the gross and net fair values of our derivative assets and liabilities and repurchase agreements, as well as the related offsetting amounts permitted under U.S. GAAP. The table also includes cash and non-cash collateral received or pledged in accordance with such arrangements. The amount of collateral presented, however, is limited to the amount of the related net derivative fair values or outstanding balances; therefore, instances of over-collateralization are excluded.

(2) See “ Note 10—Stockholders’ Equity ” for the effects of cash flow and net investment hedges on AOCI and amounts reclassified to net income, net of tax. (3) We recognized a loss of $172 million and a gain of $75 million on foreign exchange contracts reclassified from AOCI for the three months ended March 31, 2019 and 2018, respectively. These amounts were entirely offset by the foreign currency transaction gains (losses) on our foreign currency denominated inter-company borrowings included non-interest income. In the next 12 months, we expect to reclassify to earnings net after-tax losses of $113 million recorded in AOCI as of March 31, 2019 . These amounts will offset the cash flows associated with the hedged forecasted transactions. The maximum length of time over which forecasted transactions were hedged was approximately seven years as of March 31, 2019 . The amount we expect to reclassify into earnings may change as a result of changes in market conditions and ongoing actions taken as part of our overall risk management strategy. Free-Standing Derivatives The net impacts to our consolidated statements of income related to free-standing derivatives are presented below for the three months ended March 31, 2019 and 2018 .

Accumulated Other Comprehensive Income Accumulated other comprehensive income primarily consists of accumulated net unrealized gains or losses associated with available for sale securities, the changes in fair value of derivatives designated as cash flow hedges, unrealized gains and losses on securities held to maturity on the transfer date from the available for sale category and foreign currency translation adjustments. Unrealized gains and losses for securities held to maturity are amortized over the remaining life of the security with no expected impact on future net income as amortization of these gains or losses will be offset by the amortization of the premium or discount created from the transfer of securities from available to sale to held to maturity. The following table includes the AOCI impacts from the adoption of accounting standards and the changes in AOCI by component for the three months ended March 31, 2019 and 2018 .

(2) In the first quarter of 2018, we made a one-time transfer of held to maturity securities with a carrying value of $9.0 billion to available for sale as a result of our adoption of ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities . This transfer resulted in an after-tax gain of $82 million ( $107 million pre-tax) to AOCI. The following table presents the impacts on net income of amounts reclassified from each component of AOCI for the three months ended March 31, 2019 and 2018 .

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	NOTE 12—FAIR VALUE MEASUREMENT Fair value, also referred to as an exit price, is defined as the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. The fair value accounting guidance provides a three-level fair value hierarchy for classifying financial instruments. This hierarchy is based on the markets in which the assets or liabilities trade and whether the inputs to the valuation techniques used to measure fair value are observable or unobservable. The fair value measurement of a financial asset or liability is assigned a level based on the lowest level of any input that is significant to the fair value measurement in its entirety. The three levels of the fair value hierarchy are described below: Level 1: Valuation is based on quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Valuation is based on observable market-based inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Valuation is generated from techniques that use significant assumptions not observable in the market. Valuation techniques include pricing models, discounted cash flow methodologies or similar techniques. The accounting guidance for fair value measurements requires that we maximize the use of observable inputs and minimize the use of unobservable inputs in determining fair value. The accounting guidance provides for the irrevocable option to elect, on a contract-by-contract basis, to measure certain financial assets and liabilities at fair value at inception of the contract and record any subsequent changes in fair value in earnings. We have not made any material fair value option elections as of or for the periods disclosed herein. The determination and classification of financial instruments in the fair value hierarchy is performed at the end of each reporting period. We consider all available information, including observable market data, indications of market liquidity and orderliness, and our understanding of the valuation techniques and significant inputs. For additional information on the valuation techniques used in estimating the fair value of our financial assets and liabilities on a recurring basis, see “Note 17—Fair Value Measurement” in our 2018 Form 10-K. Fair Value Governance and Control We have a governance framework and a number of key controls that are intended to ensure that our fair value measurements are appropriate and reliable. Our governance framework provides for independent oversight and segregation of duties. Our control processes include review and approval of new transaction types, price verification, and review of valuation judgments, methods, models, process controls and results. Groups independent of our trading and investing functions participate in the review and validation process. Tasks performed by these groups include periodic verification of fair value measurements to determine if assigned fair values are reasonable, including comparing prices from vendor pricing services to other available market information. Our Fair Value Committee (“FVC”), which includes representation from business areas, Risk Management and Finance, provides guidance and oversight to ensure an appropriate valuation control environment. The FVC regularly reviews and approves our fair valuations to ensure that our valuation practices are consistent with industry standards and adhere to regulatory and accounting guidance. We have a model policy, established by an independent Model Risk Office, which governs the validation of models and related supporting documentation to ensure the appropriate use of models for pricing and fair value measurements. The Model Risk Office validates all models and provides ongoing monitoring of their performance. The fair value governance process is set up in a manner that allows the Chairperson of the FVC to escalate valuation disputes that cannot be resolved by the FVC to a more senior committee called the Valuations Advisory Committee (“VAC”) for resolution. The VAC is chaired by the Chief Financial Officer and includes other members of senior management. The VAC convenes to review escalated valuation disputes. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table displays our assets and liabilities measured on our consolidated balance sheets at fair value on a recurring basis as of March 31, 2019 and December 31, 2018 . Table 12.1 : Assets and Liabilities Measured at Fair Value on a Recurring Basis March 31, 2019 Fair Value Measurements Using Netting Adjustments (1) (Dollars in millions) Level 1 Level 2 Level 3 Total Assets: Securities available for sale: U.S. Treasury securities $ 4,127 $ 0 $ 0 — $ 4,127 RMBS 0 34,431 434 — 34,865 CMBS 0 5,313 9 — 5,322 Other securities 198 1,376 0 — 1,574 Total securities available for sale 4,325 41,120 443 — 45,888 Other assets: Derivative assets (2) 1 1,178 42 $ (512 ) 709 Other (3) 306 0 155 — 461 Total assets $ 4,632 $ 42,298 $ 640 $ (512 ) $ 47,058 Liabilities: Other liabilities: Derivative liabilities (2) $ 1 $ 838 $ 36 $ (421 ) $ 454 Total liabilities $ 1 $ 838 $ 36 $ (421 ) $ 454 December 31, 2018 Fair Value Measurements Using Netting Adjustments (1) (Dollars in millions) Level 1 Level 2 Level 3 Total Assets: Securities available for sale: U.S. Treasury securities $ 6,144 $ 0 $ 0 — $ 6,144 RMBS 0 33,212 433 — 33,645 CMBS 0 4,729 10 — 4,739 Other securities 219 1,403 0 — 1,622 Total securities available for sale 6,363 39,344 443 — 46,150 Other assets: Derivative assets (2) 0 1,501 38 $ (1,079 ) 460 Other (3) 265 0 158 — 423 Total assets $ 6,628 $ 40,845 $ 639 $ (1,079 ) $ 47,033 Liabilities: Other liabilities: Derivative liabilities (2) $ 0 $ 1,153 $ 48 $ (287 ) $ 914 Total liabilities $ 0 $ 1,153 $ 48 $ (287 ) $ 914 __________ (1) Represents balance sheet netting of derivative assets and liabilities, and related payables and receivables for cash collateral held or placed with the same counterparty. See “ Note 9—Derivative Instruments and Hedging Activities ” for additional information. (2) Does not reflect $7 million and $2 million recognized as a net valuation allowance on derivative assets and liabilities for non-performance risk as of March 31, 2019 and December 31, 2018 , respectively. Non-performance risk is included in derivative assets and liabilities, which are part of other assets and liabilities on the consolidated balance sheets, and is offset through non-interest income in the consolidated statements of income. (3) As of March 31, 2019 and December 31, 2018 , other includes retained interests in securitizations of $155 million and $158 million , deferred compensation plan assets of $305 million and $264 million , and equity securities of $1 million and $1 million , respectively. Level 3 Recurring Fair Val ue Rollforward The table below presents a reconciliation for all assets and liabilities measured and recognized at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three months ended March 31, 2019 and 2018 . Generally, transfers into Level 3 were primarily driven by the usage of unobservable assumptions in the pricing of these financial instruments as evidenced by wider pricing variations among pricing vendors and transfers out of Level 3 were primarily driven by the usage of assumptions corroborated by market observable information as evidenced by tighter pricing among multiple pricing sources.

Gains (losses) on derivatives are included as a component of net interest income or non-interest income in our consolidated statements of income. (2) Net unrealized gains included in other comprehensive income related to Level 3 securities available for sale still held as of March 31, 2019 were $10 million . (3) Includes derivative assets and liabilities of $42 million and $36 million , respectively, as of March 31, 2019 , and $36 million and $45 million , respectively, as of March 31, 2018 . Significant Level 3 Fair Value Asset and Liability Inputs Generally, uncertainties in fair value measurements of financial instruments, such as changes in unobservable inputs, may have a significant impact on fair value. Certain of these unobservable inputs will, in isolation, have a directionally consistent impact on the fair value of the instrument for a given change in that input. Alternatively, the fair value of the instrument may move in an opposite direction for a given change in another input. In general, an increase in the discount rate, default rates, loss severity and credit spreads, in isolation, would result in a decrease in the fair value measurement. In addition, an increase in default rates would generally be accompanied by a decrease in recovery rates, slower prepayment rates and an increase in liquidity spreads. Techniques and Inputs for Level 3 Fair Value Measurements The following table presents the significant unobservable inputs used to determine the fair values of our Level 3 financial instruments on a recurring basis. We utilize multiple vendor pricing services to obtain fair value for our securities. Several of our vendor pricing services are only able to provide unobservable input information for a limited number of securities due to software licensing restrictions. Other vendor pricing services are able to provide unobservable input information for all securities for which they provide a valuation. As a result, the unobservable input information for the securities available for sale presented below represents a composite summary of all information we are able to obtain. The unobservable input information for all other Level 3 financial instruments is based on the assumptions used in our internal valuation models. Table 12.3 : Quantitative Information about Level 3 Fair Value Measurements Quantitative Information about Level 3 Fair Value Measurements (Dollars in millions) Fair Value at March 31, Significant Valuation Techniques Significant Unobservable Inputs Range Weighted Average (1) Securities available for sale: RMBS $ 434 Discounted cash flows (vendor pricing) Yield 2-15% 5% CMBS 9 Discounted cash flows (vendor pricing) Yield 3% 3% Other assets: Retained interests in securitization (2) 155 Discounted cash flows Life of receivables (months) 1-54 N/A Net derivative assets (liabilities) 6 Discounted cash flows Swap rates 2% 2% Quantitative Information about Level 3 Fair Value Measurements (Dollars in millions) Fair Value at December 31, 2018 Significant Valuation Techniques Significant Unobservable Inputs Range Weighted Average (1) Securities available for sale: RMBS $ 433 Discounted cash flows (vendor pricing) Yield 3-11% 5% CMBS 10 Discounted cash flows (vendor pricing) Yield 3% 3% Other assets: Retained interests in securitization (2) 158 Discounted cash flows Life of receivables (months) 3-56 N/A Net derivative assets (liabilities) (10 ) Discounted cash flows Swap rates 3% 3% __________ (1) Weighted averages are calculated by using the product of the input multiplied by the relative fair value of the instruments. (2) Due to the nature of the various mortgage securitization structures in which we have retained interests, it is not meaningful to present a consolidated weighted average for the significant unobservable inputs. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis We are required to measure and recognize certain assets at fair value on a nonrecurring basis on the consolidated balance sheets. These assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, from the application of lower of cost or fair value accounting or when we evaluate for impairment). The following table presents the carrying value of the assets measured at fair value on a nonrecurring basis and still held as of March 31, 2019 and December 31, 2018 , and for which a nonrecurring fair value measurement was recorded during three and twelve months then ended. Table 12.4 : Nonrecurring Fair Value Measurements March 31, 2019 Estimated Fair Value Hierarchy Total (Dollars in millions) Level 2 Level 3 Loans held for investment $ 0 $ 191 $ 191 Loans held for sale 192 0 192 Other assets (1) 0 55 55 Total $ 192 $ 246 $ 438 December 31, 2018 Estimated Fair Value Hierarchy Total (Dollars in millions) Level 2 Level 3 Loans held for investment $ 0 $ 129 $ 129 Loans held for sale 38 0 38 Other assets (1) 0 100 100 Total $ 38 $ 229 $ 267 __________ (1) As of March 31, 2019 , other assets included equity investments accounted for under the measurement alternative of $5 million , repossessed assets of $49 million and long-lived assets held for sale of $1 million . As of December 31, 2018 , other assets included equity investments accounted for under the measurement alternative of $24 million , foreclosed property and repossessed assets of $57 million and long-lived assets held for sale of $19 million . In the above table, loans held for investment are generally valued based in part on the estimated fair value of the underlying collateral and the non-recoverable rate, which is considered to be a significant unobservable input. The non-recoverable rate ranged from 0% to 60% , with a weighted average of 7% , and from 0% to 84% , with a weighted average of 33% , as of March 31, 2019 and December 31, 2018 , respectively. The weighted average non-recoverable rate is calculated based on the estimated market value of the underlying collateral. The significant unobservable inputs and related quantitative information related to fair value of the other assets are not meaningful to disclose as they vary significantly across properties and collateral. The following table presents total nonrecurring fair value measurements for the period, included in earnings, attributable to the change in fair value relating to assets that are still held at March 31, 2019 and 2018 .

Segment Reporting [Abstract]
Segment Reporting Disclosure	NOTE 13—BUSINESS SEGMENTS AND REVENUE FROM CONTRACTS WITH CUSTOMERS Our principal operations are organized into three major business segments, which are defined primarily based on the products and services provided or the type of customer served: Credit Card, Consumer Banking and Commercial Banking. The operations of acquired businesses have been integrated into our existing business segments. Certain activities that are not part of a segment, such as management of our corporate investment portfolio, asset/liability management by our centralized Corporate Treasury group and residual tax expense or benefit to arrive at the consolidated effective tax rate that is not assessed to our primary business segments, are included in the Other category. Basis of Presentation We report the results of each of our business segments on a continuing operations basis. The results of our individual businesses reflect the manner in which management evaluates performance and makes decisions about funding our operations and allocating resources. Business Segment Reporting Methodology The results of our business segments are intended to present each segment as if it were a stand-alone business. Our internal management and reporting process used to derive our segment results employs various allocation methodologies, including funds transfer pricing, to assign certain balance sheet assets, deposits and other liabilities and their related revenue and expenses directly or indirectly attributable to each business segment. Our funds transfer pricing process provides a funds credit for sources of funds, such as deposits generated by our Consumer Banking and Commercial Banking businesses, and a funds charge for the use of funds by each segment. Due to the integrated nature of our business segments, estimates and judgments have been made in allocating certain revenue and expense items. Transactions between segments are based on specific criteria or approximate third-party rates. We regularly assess the assumptions, methodologies and reporting classifications used for segment reporting, which may result in the implementation of refinements or changes in future periods. We provide additional information on the allocation methodologies used to derive our business segment results in “Note 18—Business Segments and Revenue from Contracts with Customers” in our 2018 Form 10-K. Segment Results and Reconciliation We may periodically change our business segments or reclassify business segment results based on modifications to our management reporting methodologies or changes in organizational alignment. In the first quarter of 2019, we made a change in how revenue is measured in our Commercial Banking business by revising the allocation of tax benefits on certain tax-advantaged investments. As such, prior period results have been recast to conform with the current period presentation. The result of this measurement change reduced the previously reported total net revenue in our Commercial Banking business by $30 million for the three months ended March 31, 2018, with an offsetting increase in the Other category. This change in measurement of our Commercial Banking revenue did not have any impact to the consolidated financial statements. The following tables present our business segment results for the three months ended March 31, 2019 and 2018 , selected balance sheet data as of March 31, 2019 and 2018 , and a reconciliation of our total business segment results to our reported consolidated income from continuing operations, loans held for investment and deposits.

(2) In the first quarter of 2019, we made a change in how revenue is measured in our Commercial Banking business by revising the allocation of tax benefits on certain tax-advantaged investments.

Revenue from Contracts with Customers The majority of our revenue from contracts with customers consists of interchange fees in our Credit Card business, service charges and other customer-related fees, and other contract revenue in our Consumer Banking and Commercial Banking businesses. Interchange fees are primarily from our Credit Card business and are recognized upon settlement with the interchange networks, net of rewards earned by customers. Service charges and other customer-related fees within our Consumer Banking business are primarily related to fees earned on consumer deposit accounts for account maintenance and various transaction-based services such as overdrafts and ATM usage. Service charges and other customer-related fees within our Commercial Banking business are mostly related to fees earned on treasury management and capital markets services. Other contract revenue consists primarily of revenue earned on certain marketing and promotional events from our auto dealers within our Consumer Banking business. Revenue from contracts with customers is included in non-interest income in our consolidated statements of income. The following tables present revenue from contracts with customers and a reconciliation to non-interest income by business segment for the three months ended March 31, 2019 and 2018 .

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies, Guarantees and Others	NOTE 14—COMMITMENTS, CONTINGENCIES, GUARANTEES AND OTHERS Commitments to Lend Our unfunded lending commitments primarily consist of credit card lines, loan commitments to customers of both our Commercial Banking and Consumer Banking businesses, as well as standby and commercial letters of credit. These commitments, other than credit card lines, are legally binding conditional agreements that have fixed expirations or termination dates and specified interest rates and purposes. The contractual amount of these commitments represents the maximum possible credit risk to us should the counterparty draw upon the commitment. We generally manage the potential risk of unfunded lending commitments by limiting the total amount of arrangements, monitoring the size and maturity structure of these portfolios, and applying the same credit standards for all of our credit activities. For unused credit card lines, we have not experienced and do not anticipate that all of our customers will access their entire available line at any given point in time. Commitments to extend credit other than credit card lines generally require customers to maintain certain credit standards. Collateral requirements and loan-to-value (“LTV”) ratios are the same as those for funded transactions and are established based on management’s credit assessment of the customer. These commitments may expire without being drawn upon; therefore, the total commitment amount does not necessarily represent future funding requirements. We also issue letters of credit, such as financial standby, performance standby and commercial letters of credit, to meet the financing needs of our customers. Standby letters of credit are conditional commitments issued by us to guarantee the performance of a customer to a third party in a borrowing arrangement. Commercial letters of credit are short-term commitments issued primarily to facilitate trade finance activities for customers and are generally collateralized by the goods being shipped to the client. These collateral requirements are similar to those for funded transactions and are established based on management’s credit assessment of the customer. Management conducts regular reviews of all outstanding letters of credit and the results of these reviews are considered in assessing the adequacy of reserves for unfunded lending commitments. The following table presents the contractual amount and carrying value of our unfunded lending commitments as of March 31, 2019 and December 31, 2018 . The carrying value represents our reserve and deferred revenue on legally binding commitments. Table 14.1 : Unfunded Lending Commitments: Contractual Amount and Carrying Value Contractual Amount Carrying Value (Dollars in millions) March 31, December 31, March 31, December 31, Credit card lines $ 352,826 $ 346,186 N/A N/A Other loan commitments (1) 35,446 34,449 $ 102 $ 95 Standby letters of credit and commercial letters of credit (2) 1,767 1,792 31 29 Total unfunded lending commitments $ 390,039 $ 382,427 $ 133 $ 124 __________ (1) Includes $1.2 billion and $1.3 billion of advised lines of credit as of March 31, 2019 and December 31, 2018 , respectively. (2) These financial guarantees have expiration dates ranging from 2019 to 2025 as of March 31, 2019 . Loss Sharing Agreements and Other Obligations Within our Commercial Banking business, we originate multifamily commercial real estate loans with the intent to sell them to the GSEs. We enter into loss sharing agreements with the GSEs upon the sale of the loans. At inception, we record a liability representing the fair value of our obligation which is subsequently amortized as we are released from risk of payment under the loss sharing agreement. If payment under the loss sharing agreement becomes probable and estimable, an additional liability may be recorded on the consolidated balance sheets and a non-interest expense may be recognized in the consolidated statements of income. The liability recognized on our consolidated balance sheets for our loss sharing agreements was $62 million and $59 million as of March 31, 2019 and December 31, 2018 , respectively. U.K. Payment Protection Insurance In the U.K., we previously sold payment protection insurance (“PPI”). In response to an elevated level of customer complaints across the industry, heightened media coverage and pressure from consumer advocacy groups, the U.K. Financial Conduct Authority (“FCA”), formerly the Financial Services Authority, investigated and raised concerns about the way the industry has handled complaints related to the sale of these insurance policies. For the past several years, the U.K.’s Financial Ombudsman Service (“FOS”) has been adjudicating customer complaints relating to PPI, escalated to it by consumers who disagree with the rejection of their complaint by firms, leading to customer remediation payments by us and others within the industry. On March 2, 2017, the FCA issued a statement that sets out final rules and guidance on the PPI complaints deadline, which has been set as August 29, 2019. The statement also provides clarity on how to handle PPI complaints under s.140A of the Consumer Credit Act, including guidance on how redress for such complaints should be calculated. The final rules and guidance came into force on August 29, 2017. In determining our best estimate of incurred losses for future remediation payments, management considers numerous factors, including (i) the number of customer complaints we expect in the future; (ii) our expectation of upholding those complaints; (iii) the expected number of complaints customers escalate to the FOS; (iv) our expectation of the FOS upholding such escalated complaints; (v) the number of complaints that fall under s.140A of the Consumer Credit Act; (vi) the number of litigation claims being pursued under s.140A of the Consumer Credit Act; and (vii) the estimated remediation payout to customers. We monitor these factors each quarter and adjust our reserves to reflect the latest data. Management’s best estimate of U.K. PPI reserve totaled $105 million and $133 million as of March 31, 2019 and December 31, 2018 , respectively. For the three months ended March 31, 2019 , no additions were made to our reserve. Other movements to the reserve were a combination of utilization of the reserve through customer refund payments and foreign exchange movements. Our best estimate of reasonably possible future losses beyond our reserve as of March 31, 2019 is approximately $100 million . Litigation In accordance with the current accounting standards for loss contingencies, we establish reserves for litigation related matters that arise from the ordinary course of our business activities when it is probable that a loss associated with a claim or proceeding has been incurred and the amount of the loss can be reasonably estimated. None of the amounts we currently have recorded individually or in the aggregate are considered to be material to our financial condition. Litigation claims and proceedings of all types are subject to many uncertain factors that generally cannot be predicted with assurance. Below we provide a description of potentially material legal proceedings and claims. For some of the matters disclosed below, we are able to estimate reasonably possible losses above existing reserves, and for other disclosed matters, such an estimate is not possible at this time. For those matters below where an estimate is possible, management currently estimates the reasonably possible future losses beyond our reserves as of March 31, 2019 are approximately $1.1 billion . Our reserve and reasonably possible loss estimates involve considerable judgment and reflect that there is still significant uncertainty regarding numerous factors that may impact the ultimate loss levels. Notwithstanding our attempt to estimate a reasonably possible range of loss beyond our current accrual levels for some litigation matters based on current information, it is possible that actual future losses will exceed both the current accrual level and the range of reasonably possible losses disclosed here. Given the inherent uncertainties involved in these matters, especially those involving governmental agencies, and the very large or indeterminate damages sought in some of these matters, there is significant uncertainty as to the ultimate liability we may incur from these litigation matters and an adverse outcome in one or more of these matters could be material to our results of operations or cash flows for any particular reporting period. Interchange In 2005, a putative class of retail merchants filed antitrust lawsuits against MasterCard and Visa and several issuing banks, including Capital One, seeking both injunctive relief and monetary damages for an alleged conspiracy by defendants to fix the level of interchange fees. Other merchants have asserted similar claims in separate lawsuits, and while these separate cases did not name any issuing banks, Visa, MasterCard and issuers, including Capital One, have entered settlement and judgment sharing agreements allocating the liabilities of any judgment or settlement arising from all interchange-related cases. The lawsuits were consolidated before the U.S. District Court for the Eastern District of New York for certain purposes and were settled in 2012. The class settlement, however, was invalidated by the United States Court of Appeals for the Second Circuit in June 2016, and the suit was separated into separate class actions seeking injunctive and monetary relief, respectively. In addition, numerous merchant groups opted out of the 2012 settlement and have pursued their own claims. The claims by the injunctive relief class have not been resolved, but the parties reached a new settlement agreement with the monetary damages class in August 2018, whereby the class would receive up to approximately $6.2 billion collectively from the defendants in exchange for a release of their claims, depending on the percentage of class plaintiffs who opt out. The trial court preliminarily approved the settlement in January 2019. Visa and MasterCard have also settled several of the opt-out cases, which required non-material payments from issuing banks, including Capital One. Visa created a litigation escrow account following its initial public offering of stock in 2008 that funds settlements for its member banks, and any settlements related to MasterCard-allocated losses have either already been paid or are reflected in Capital One’s reserves. Mortgage Representation and Warranty We face residual exposure related to subsidiaries that originated residential mortgage loans and sold these loans to various purchasers, including purchasers who created securitization trusts. In connection with their sales of mortgage loans, these subsidiaries entered into agreements containing varying representations and warranties about, among other things, the ownership of the loan, the validity of the lien securing the loan, the loan’s compliance with any applicable criteria established by the purchaser, including underwriting guidelines and the existence of mortgage insurance, and the loan’s compliance with applicable federal, state and local laws. Each of these subsidiaries may be required to repurchase mortgage loans or indemnify certain purchasers and others against losses they incur in the event of certain breaches of these representations and warranties. The substantial majority of our representation and warranty exposure has been resolved through litigation, and our remaining representation and warranty exposure is almost entirely litigation-related. Accordingly, we establish litigation reserves for representation and warranty losses that we consider to be both probable and reasonably estimable. The reserve process relies heavily on estimates, which are inherently uncertain, and requires the application of judgment. Our reserves and estimates of reasonably possible losses could be impacted by claims which may be brought by securitization trustees and sponsors, bond-insurers, investors, and GSEs, as well as claims brought by governmental agencies. Anti-Money Laundering Capital One is subject to an open consent order with the Office of the Comptroller of the Currency (“OCC”) dated July 10, 2015 relating to our anti-money laundering (“AML”) program. In October 2018, Capital One paid a civil monetary penalty of $100 million to resolve the monetary component of the AML consent order. Capital One continues to be investigated by the New York District Attorney’s Office, the Department of Justice and the Financial Crimes Enforcement Network (“FinCEN”) of the U.S. Department of Treasury primarily with respect to certain former check casher clients of the Commercial Banking business and Capital One’s AML program. Capital One is cooperating with all agencies involved in the investigation. We are in discussions with FinCEN to explore a potential regulatory resolution of its investigation, which could include a monetary penalty. Other Pending and Threatened Litigation

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”).
Use of Estimates	The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and in the related disclosures. These estimates are based on information available as of the date of the consolidated financial statements. While management makes its best judgments, actual amounts or results could differ from these estimates. In the opinion of management, all normal, recurring adjustments have been included for a fair statement of this interim financial information.
New Accounting Standards	Newly Adopted Accounting Standards Standard Guidance Adoption Timing and Financial Statements Impacts Premium Amortization on Callable Debt Accounting Standards Update (“ASU”) No. 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities Issued March 2017 Shortens the amortization period from the contractual life to the earliest call date for certain purchased callable debt securities held at a premium. We adopted this guidance in the first quarter of 2019 using the modified retrospective method of adoption. Our adoption of this standard did not have a material impact on our consolidated financial statements. Leases ASU No. 2016-02, Leases (Topic 842) Issued February 2016 Requires lessees to recognize right of use assets and lease liabilities on their consolidated balance sheets and disclose key information about all their leasing arrangements, with certain practical expedients. We adopted this guidance in the first quarter of 2019, using the modified retrospective method of adoption without restating prior periods. We elected the practical expedients that permitted us to not reassess the lease classification of existing leases, whether existing contracts contain a lease or the treatment of initial direct costs on existing leases. Upon adoption, we recorded a lease liability of $1.9 billion and right of use asset of $1.6 billion, which is net of other lease-related balances. Accounting Standards Issued but Not Adopted as of March 31, 2019 Standard Guidance Adoption Timing and Financial Statements Impacts Cloud Computing ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract Issued August 2018 Aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Effective January 1, 2020, with early adoption permitted, using either the retrospective or prospective method of adoption. We plan to adopt the standard on its effective date and are currently evaluating the expected impact of such adoption. Goodwill Impairment Test Simplification ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment Issued January 2017 Eliminates the second step from the current goodwill impairment test. Under the current guidance, the first step compares a reporting unit’s carrying value to its fair value. If the carrying value exceeds fair value, an entity performs the second step, which assigns the reporting unit’s fair value to its assets and liabilities, including unrecognized assets and liabilities, in the same manner as required in purchase accounting. Under the new guidance, any impairment of a reporting unit’s goodwill is determined based on the amount by which the reporting unit’s carrying value exceeds its fair value, limited to the amount of goodwill allocated to the reporting unit. Effective January 1, 2020, with early adoption permitted, using the prospective method of adoption. We plan to adopt the standard on its effective date and do not expect such adoption to have a material impact on our consolidated financial statements. Standard Guidance Adoption Timing and Financial Statements Impacts Current Expected Credit Loss (“CECL”) ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Issued June 2016 Requires the use of current expected credit loss model that is based on expected rather than incurred losses to determine our allowance for credit losses on financial assets measured at amortized cost, certain net investments in leases and certain off-balance sheet arrangements. Replaces current accounting for PCI and impaired loans. Amends the other-than-temporary impairment model for available for sale debt securities to require that credit losses (and subsequent recoveries) be recorded through an allowance approach, rather than through permanent write-downs for credit losses and subsequent accretion of positive changes through interest income over time. Effective January 1, 2020, with early adoption permitted no earlier than January 1, 2019, using the modified retrospective method of adoption. We plan to adopt the standard on its effective date. We have established a company-wide, cross-functional governance structure for our implementation of this standard. We continue to evaluate industry accounting interpretations, data requirements and necessary changes to our credit loss estimation methods, processes, systems and controls. We have commenced limited parallel testing and expect to perform multiple tests of our full end-to-end allowance process prior to adopting the standard. We continue to assess the potential impact on our consolidated financial statements, related disclosures and regulatory capital. We currently expect our adoption of this guidance will result in an increase to our reserves for credit losses on financial instruments due to the requirement to record expected losses over the remaining contractual lives of our financial instruments; however, the actual impact will depend on the characteristics of our financial instruments, economic conditions, and our economic and loss forecasts at the adoption date.
Offsetting of Financial Assets and Liabilities	Balance Sheet Offsetting of Financial Assets and LiabilitiesDerivative contracts and repurchase agreements that we execute bilaterally in the OTC market are generally governed by enforceable master netting arrangements where we generally have the right to offset exposure with the same counterparty. Either counterparty can generally request to net settle all contracts through a single payment upon default on, or termination of, any one contract. We elect to offset the derivative assets and liabilities under netting arrangements for balance sheet presentation where a right of setoff exists. For derivative contracts entered into under master netting arrangements for which we have not been able to confirm the enforceability of the setoff rights, or those not subject to master netting arrangements, we do not offset our derivative positions for balance sheet presentation.

Schedule of Assets and Liabilities Measured at Fair Value on Recurring Basis Quantitative Information	The following table presents the significant unobservable inputs used to determine the fair values of our Level 3 financial instruments on a recurring basis. We utilize multiple vendor pricing services to obtain fair value for our securities. Several of our vendor pricing services are only able to provide unobservable input information for a limited number of securities due to software licensing restrictions. Other vendor pricing services are able to provide unobservable input information for all securities for which they provide a valuation. As a result, the unobservable input information for the securities available for sale presented below represents a composite summary of all information we are able to obtain. The unobservable input information for all other Level 3 financial instruments is based on the assumptions used in our internal valuation models.

Accordingly, we present our Commercial Banking revenue and yields on a taxable-equivalent basis, calculated using the federal statutory tax rate of 21% and state taxes where applicable, with offsetting reductions to the Other category. (2) In the first quarter of 2019, we made a change in how revenue is measured in our Commercial Banking business by revising the allocation of tax benefits on certain tax-advantaged investments. As such, prior period results have been recast to conform with the current period presentation. The result of this measurement change reduced the previously reported total net revenue in our Commercial Banking business by $30 million for the three months ended March 31, 2018, with an offsetting increase in the Other category.
